Do you have a suggestion for what a responsive UI for showing 8 concurrent filmstrips would look like? I can't think of a good way to make it work and still keep the ability to easily compare across pages (though supporting wide screens and showing more frames would be worthwhile).

With the advent of prefetch and prerender (which have very significant impact on load times/CPU load/etc), and their varying implementation between browsers, it'd be very useful to see the impact of these by having a test run in which a sequence of at least two (perhaps more) pages are accessed, with a small delay between them.

Bonus marks if there is an option to disable the pre* features for a particular run - it can be done in all browsers that I'm aware of by turning off "preload"/"network prediction"/"prefetching".

Your system does not detect our two CDN's thus are scores are biased
We would like to be able to declare the IP adresses of both our CDN (content distribution network) servers. Either manually in advanced settings, or better still, in a customer profile that can save the most usual settings.

Would like to be able to get the metrics posted from the Data Plot Summary as XML / JSON. The Median, Mean, STDev scores are available, but would be helpful to grab IQR range and Coefficient of Variation scores to capture consistency of performance. Can recalculate programmatically via the XML results using the raw metrics but since it's already available via the data plot page, it makes sense to reuse those calculations and expose via XML.

1) Identify/Display http2.0/SPDY/QUIC in the request overview
2) Display custom response-headers as one or more columns in the "request details" would be awesome-Things like "X-WebServer" or X-Cache-Hit etc. etc.

It's pretty high on the list to implement recurring scheduled testing but mostly for the private install version. I'll probably enable it on the public version for a handfull of urls for "approved" registered members but need to be a little careful to protect the testing capacity.
